The color of the lenticels of the fruit is FAN4 160B. The lenticels of the wood are clearly projecting, projections can be definitely felt upon palpating of the wood. Very many lenticels are present on the wood. The shape of the lenticels is dot like/circular up to globular/flattened. The lenticels on the trunk have a length of up to 2.2 mm and have a height of from 1 to 1.5 mm. In contrast, the lenticels on the branches are only from about 1.0 to 1.6 mm and are therefore smaller. The color of the lenticels on the trunk and on the branches is FAN4 155A to 155B. The stability of the propagation was considered. The tree ‘Fuji Fubrax’ shows a 99 percent variety originality in commercial installations. The so-called regression rate or reversion rate is only 1 percent. The typical properties of ‘Fuji Fubrax’ have not changed in the course of propagation. The observed plant retains its distinctive characteristics and reproduces true to type in successive generations. ‘Fuji Fubrax’ is reproduced by chip budding.
The leaves of ‘Fuji Fubrax’ have the following properties: The color of the top side of the leaf is FAN3 137A to 137B for younger trees. The color of the top side of the leaf is very dark 138a for older trees. The color of the bottom side of the leaf is FAN3, 137C to 138A for younger trees.

The width of the kernel at the widest point is about 5.5 mm, which occurs at a distance of a third from the heart of the kernel. The width of the kernel at about two thirds of a distance from the heart of the kernel is about 3.5 mm. The thickness of the kernel of ‘Brak’ is from about 2.8 to 3 mm. The color of the kernel is FAN4 166C. Stripes or areas with darker color are present at the edges of the kernels and exhibit a darker color FAN4 166A to 166B. The interior of the kernel shows the color FAN4 155B.
The colors of the written description override the colors of the pictures. The colors were compared with The Royal Horticultural Society Color Chart as follows: The bottom side of a leaf had the color Fan 3, 137C.
The top side of a leaf had the color Fan 3, 139A. The trunk of two year old trees had the color Fan4, N200B. The trunk of five year old trees had the color Fan4, N200C. The branches of the trees had the color Fan4, N200C. The lenticels of the trees had the color Fan4, 198D. The base color of the apple was Fan3, 144D. The color of the striping of the apple was Fan1, 45A. The color of the flesh of an apple fruit was Fan1, 13D. The color of the stalk or pedicel of an apple was Fan3, 144D. The color of a closed flower was Fang, N67C. The color of an open flower was Fan4, N155A. The color of the seeds was Fan4, 1663. The color of the cavity of the calyx was Fan 3, 145A. The color of the cavity of the stalk or stem cavity was Fan 3, 145A. Two year old trees ‘Fuji Fubrax’were observed at 30 cm away from the grafting location to have the color FAN4 177A and 130 cm away from the grafting location to have the color FAN4 177a to 177B. This means that during a young phase of the ‘Fuji Fubrax’tree trunk and branches have the color FAN4 177A. The trunk and the old branches assume the color grey (FAN4 2013) more and more with increasing age, while the young wood (one to two years old) of the branches retains the color FAN4 177A.
A comparison was performed between ‘Myra (Nr. 9,845) and ‘Triple E’ (Nr. 12,219) and ‘Fuji Fubrax’. An immediate comparison is difficult, since the climatic conditions are different and the environmental conditions are different. The color indications for ‘Fuji Fubrax’ and ‘Triple E’ are based on the RHS color chart, the color indications of ‘Myra’ are based on the Munsell color code. The covering color of the ‘Fuji Fubrax’ was dark Ruby red (45A). The covering color of ‘Myra’ was pinkish red 39-12 to 39-13. The covering color of ‘Triple E’ was Red 53B. The striping of ‘Fuji Fubrax’ was uniform and not too wide. The striping of ‘Myra’ was slightly darker with pinkish-red stripes. ‘Triple E’ did not exhibit any stripes. The color development of the apple ‘Fuji Fubrax’ occurred early, some weeks before ‘Fuji’.
The color development of the apple ‘Myra’ occurred 14 days earlier than that of standard ‘Fuji’ and there were red striped strains. The fruit maturation of ‘Fuji Fubrax’ was homogeneous. One can harvest all the crop of ‘Fuji Fubrax’ in a first picking because of uniform apples and because all ‘Fuji Fubrax’ apples have the same properties. Even those apples in the shadow areas of the tree and all apples ‘Fuji Fubrax’ have the same properties over the complete surface of the apple. This is associated with some advantages including a maximum of two pickings, uniform apples, better storage properties.
The fruit maturation of ‘Myra’ apples was seven days earlier than the fruit maturation of red striped strains. The fruit maturation of ‘Triple E’ apples was 10 to 14 days before “BC2”. The ‘Triple E’ apples growing in the shadow are more of a yellow green color (154C). The color of the ‘Fuji Fubrax’ leaves is very dark (139A). The color of the ‘Myra’ leaves is (21-14). The color of the ‘Triple E’ leaves is (138A). The ratio of the length to the width of the ‘Fuji Fubrax’ leaves is about 1.6:1 and the leaves are broad. The length of the ‘Triple E’ leaves is 8.4 cm and the width of ‘Triple E’ leaves is 3.2 cm. The color of the flesh of the ‘Fuji Fubrax’ apple fruit was (158A). The color of the flesh of ‘Triple E’ was (158D to 155D).
Comparison of the properties of ‘Fuji Fubrax’ with those of ‘Fuji’ apples: The point in time of flowering for ‘Fuji Fubrax’ is the same as the time of flowering of ‘Fuji’. The growth speed of ‘Fuji Fubrax’ is the same as the growth speed of ‘Fuji’. The leaf color of ‘Fuji Fubrax’ apples is dark green. The leaf color of ‘Fuji’ is light green. The leaf size of ‘Fuji Fubrax’ is large, the leaf size of ‘Fuji’ is medium. The tree habit of ‘Fuji Fubrax’ shows steep sticks. The tree habit of ‘Fuji’ shows more flat sticks. The vigor of the ‘Fuji Fubrax’ tree is strong. The vigor of the ‘Fuji’ tree is medium. The size of the lenticels on wood of the ‘Fuji Fubrax’ tree are large. The size of the lenticels on wood of the ‘Fuji’ tree are medium. The color of the flesh of the fruit of ‘Fuji Fubrax’ is yellow. The color of the flesh of the fruit of ‘Fuji’ is white green. The color of the over-color of the skin of the ‘Fuji Fubrax’ fruit is brightly dark ruby-red. The color of the over-color of the skin of the ‘Fuji’ fruit is slightly orange-red. The pattern of the over-color of the skin of the ‘Fuji Fubrax’ fruit is blush striped. The pattern of the over-color of the skin of the ‘Fuji’ fruit is washed out-striped. The amount of the over color of the skin of the ‘Fuji Fubrax’ fruit is very high including in the shadow zone. The amount of the over-color of the skin of the ‘Fuji’ fruit is medium and in the shadow zone the color is green. The brix of ‘Fuji Fubrax’ shows a high amount of sugar. The brix of ‘Fuji’ shows a lower amount of sugar. The percentage of salable fruits of ‘Fuji Fubrax’ is high (95 percent). The percentage of salable fruits of ‘Fuji’ is medium (40 percent).
The fruits of ‘Fuji Fubrax’ growing up in the shadow are colored red. The fruits of ‘Fuji’ growing up in the shadow are colored green. A characteristic feature of the tree ‘Fuji Fubrax’ relative to the tree ‘Fuji’ is the ruby-red color of the fruit and the stripes of ‘Fuji Fubrax’. All apples of the variety ‘Fuji Fubrax’ are colored over their complete surface, even those located in the shadow region of the tree. Particularly remarkable is the coloration of the ‘Fuji Fubrax’ apples in the cavity of the calyx and in the cavity of the stalk or stem cavity of the apples. Also, Furbax develops the red over color some weeks before Fuji. Based on these features of the ‘Fuji Fubrax’ apples, there is one picking and a maximum of two pickings of the apples. The first picking harvests the largest part of the fruits. The harvest of the ‘Fuji Fubrax’ apples occurs with optimum inner values of the ‘Fuji Fubrax’ apple. The ‘Fuji Fubrax’ apple has a higher percentage of uniform and marketable product as compared to ‘Fuji’ apples. The ‘Fuji Fubrax’ apple exhibits a better storage behavior and for example less water core and less brown coloring of the fruit flesh as compared with ‘Fuji’ apples. The shelf-life of the ‘Fuji Fubrax’ apple is extended relative to the shelf-life of ‘Fuji’ apples. There is less rust formation with ‘Fuji Fubrax’ apples as compared with ‘Fuji’ apples. It is another characterizing feature of the ‘Fuji Fubrax’ apple tree that the apples color very early on the tree as compared to the variety ‘Fuji’. In a tree nursery, the ‘Fuji Fubrax’ tree has better rates of grafting in the course of asexual propagation, exhibits a stronger growth and a more uniform growing in comparison with a ‘Fuji’ tree. 95 percent of the fruits are harvested in the first picking with ‘Fuji Fubrax’ trees. The part of uniformly looking and therefore marketable apples is higher as compared to ‘Fuji’; from 65 to 75 percent of the apples are of a size from 80 to 90 mm. All 100 percent of the ‘Fuji Fubrax’ apples are of good color. ‘Fuji Fubrax’ can be harvested at an optimum point in time of harvesting. ‘Fuji Fubrax’ has reached the highest coloration of the covering color at that point in time, where the scientifically determined optimum and ideal internal values of the fruit (pressure, sugar, acidity, starch) have been reached. This is in contrast not the case with ‘Fuji’: the ‘Fuji’ apples have to hang for a longer time on the tree, surpass the ideal harvesting values and therewith the optimum point in time of harvesting until the ‘Fuji’ apple reaches a red coloration. ‘Fuji Fubrax’ apples exhibit during storage less damages such as water core and brown discoloration of the flesh based on the optimum harvesting point in time, the ‘Fuji’ apples in comparison exhibit a higher water core. ‘Fuji Fubrax’ apples are not so rusted on the tree as are ‘Fuji’ apples. The ruby-red covering color of the ‘Fuji Fubrax’ apples develops very early on a comparative scale with ‘Fuji’ apples. The component of covering color of ‘Fuji Fubrax’ apples is at about 95 percent about twice as high as is the case with standard ‘Fuji’ apples.
The lenticels of ‘Fuji Fubrax’ on the wood of the trunk and of the branches are particularly characterizing and clearly distinguish a ‘Fuji Fubrax’ tree from a ‘Fuji’ tree. The leaves of the ‘Fuji Fubrax’ tree are darker as compared to the leaves of the ‘Fuji’ tree.
The observed color of the over color of ‘Fuji Fubrax’ apples is lightly ruby-red. The amount of color of over-color of the skin is very high, also the back sides of the ‘Fuji Fubrax’ apples are well colored. Even ‘Fuji Fubrax’ apples in the shadow zone of the tree are colored. Even though the ‘Fuji Fubrax’ apples are almost 100 percent colored, the apples still show stripes.
Coloration of the fruits begins some weeks earlier than in normal ‘Fuji’. Six weeks before harvesting time, ‘Fuji’ apples are still almost green, while ‘Fuji Fubrax’ apples are nicely colored up to 50 percent.
